I like Rafael Lorano-Hemmer’s projects; his Open Air will be installed on the Parkway from September 20 through October 14 as part of the 2012 Live Arts Festival. While you wait, watch this video of his project Seismoscope 2: Abu Hamid Muhammad ibn Muhammad al-Ghazali, which explains itself as you go through.

Open Air runs September 20 through October 14 on the Benjamin Franklin Parkway, Center City to Fairmount. 9:00 to 11:00 pm every night, free!
